以5年生橄榄作砧木嫁接11个橄榄优树无性系,对生长、开花、结果、果实性状等进行观测及分析,结果表明:无性系间的每枝花穗数、每枝挂果数与小区产量等性状均存在显著或极显著差异,无性系与年份间互作效应也存在一定的差异,表明橄榄开花、结果性状存在遗传差异,一些无性系对气候条件变化反应敏感。采用因子分析法评选出g18、g20、g26为优良品系,综合得分分别为45.97、45.16和43.69,产量比CK分别提高9.50倍、8.61倍和8.64倍,比参试无性系的平均值分别提高178.15%、154.49%和155.44%。 Five-year-old olives were used as rootstocks for grafting eleven elm-tree clones. The growth, flowering, fruiting characters and so on were observed and analyzed. The results showed that the number of spikes per spike, There was a significant or extremely significant difference between the two clones. The interaction effect between clones and years also showed some differences, which indicated that there were genetic differences between flowering and fruit traits in olives. Some clones were sensitive to changes in climatic conditions. The results of factor analysis showed that g18, g20 and g26 were excellent lines with comprehensive scores of 45.97, 45.16 and 43.69, respectively. The yield was increased by 9.50 times, 8.61 times and 8.64 times than that of CK respectively, which was 178.15 higher than that of the tested clones respectively %, 154.49% and 155.44%.
